Re: recoil...30 cals
All you need to do is buy some gun that is in the 5000+ foot pounds of energy class without a brake and then all your .300's will seem like a plinking gun.
All I can take is about 20 shots of 400-500 grain bullets out of .458 win mag. But then when I pick up my little guns I don't even flinch.
My buddy just had to buy a 30-378 when they first came out. 26 inch bull barrel Weatherby. When he started pouring 110-120 grains of powder to it, it was really a fire breather. This was going to be his smaller game Safari gun and when he got back he was going to install some kind of 28 inch barrel and work on his long range hunting skills. He had seen the Mule deer of the lifetime once here in Nevada and it was just too far away to shoot at reliably with the equipment he had. It would have been a 1000 yard shot. So he just watched it wonder off in the spotting scope. I pounded out about 4-5 BR shots with 200 gr. and it needed a cool down period. He ask me what I thought?
Any way my true opinion on any of the Ultra mag weapons is get a good stock with very little drop. That way the recoil is straight back and not climbing to cause scope rings on your eye brough. Heavy barrels absorb the recoil and heat. I don't like brakes because of the additional rear or 90 degree noise. Sometimes you don't have the time to put on the ear muffs. I told him my BR shooting vest has built in padding, that and correct gun placement is all you need. I had him shoot my .458 BR quite a few times and he said that it did infact get him over any flinching with a small 30-378
He went on his Safari without a brake and took my .458 with max loaded 500 grain Barnes bullets. He one shot the present African Big Five
.270 Ackley improved 29 inch 1.250 dia. target barrel 7mm STW 28 inch 1.250 target barrel. I also love my .458 mag for varmints and the biggest game in the world.
